It is a one-sided cognition that the effect of various disinfectants is influenced by the concentration. Improper use of disinfectant, such as high concentration, has the following disadvantages:

 

1. Costs may increase.

 

2. If the concentration of some disinfectants is too high, the bactericidal effect will be affected. For example, 60% - 80% ethanol solution has the strongest bactericidal effect. If the concentration is too high, the protein on the bacterial surface will dehydrate and coagulate, thus forming a protective film on the bacterial surface, and the disinfectant will not continue to enter the bacterial interior to play a role.

 

3. Some disinfectants are corrosive, for example, chlorine containing disinfectants will corrode metals when they are more than 500mg / L.

 

4. For users, it may increase the risk of chemical occupational exposure.

 

In most cases, each disinfection product has a specific purpose and fixed use method. Therefore, when using, we should carefully read the commodity label to ensure that the products for the intended use are correctly selected and the use method is correct and effective.
